A DOM-based reflected Cross-Site Scripting (XSS) vulnerability exists in Elementor's Elementor Website Builder plugin, affecting all versions up to 3.5.5. This vulnerability allows attackers to execute arbitrary scripts in the context of the user's browser session, leading to potential data theft or unauthorized actions on behalf of the user.
With a CVSS score of 4.7, this vulnerability is classified as medium severity. The risk to organizations includes possible exposure of sensitive user data and the exploitation of the affected application to perform malicious actions. As this vulnerability requires user interaction to trigger, it may be less likely to be exploited in automated attacks but remains a significant risk.
Currently, there are known exploits available for this vulnerability, indicating that attackers may actively seek to leverage it. Organizations should prioritize patching the affected plugin versions immediately to mitigate this risk.
Organizations using the Elementor Website Builder should assess their plugin versions against the latest updates and schedule remediation as a priority to protect their users and data.
Vulnerability Details
The vulnerability, identified as CVE-2022-29455, is characterized as a DOM-based reflected Cross-Site Scripting (XSS). The CVSS score for this vulnerability is 4.7, indicating a medium severity level. It is associated with Elementor's Website Builder plugin versions up to 3.5.5. The vulnerability was officially published on June 13, 2022.
This vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation ('XSS'). The attack vector is network-based, and it requires low complexity with no privileges needed to exploit. User interaction is required, making it an interesting case for attackers targeting unsuspecting users.
Technical Analysis
The root cause of CVE-2022-29455 lies in the inadequate validation of user inputs in the Elementor Website Builder plugin. Attackers can craft malicious payloads that, when executed through a vulnerable instance, will execute arbitrary JavaScript code within the user's browser.
The attack vector is network-based, allowing exploitation through crafted URLs shared with potential victims. The attack complexity is low due to the straightforward nature of XSS attacks, requiring only that the victim clicks on a malicious link.
No special privileges are required to exploit this vulnerability, making it accessible to a wide range of attackers. However, user interaction is needed, as the victim must engage with the malicious link.
The impact on confidentiality is none, but integrity is partially compromised as attackers can manipulate data in the user's session. Availability remains unaffected.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant. Attackers leveraging this XSS vulnerability could steal session cookies, allowing them to hijack user accounts or perform actions on behalf of the user without their consent.
Risk to organizations includes unauthorized access to sensitive information, loss of user trust, and potential legal ramifications if user data is compromised. Given the medium severity score, organizations should assess the potential blast radius and prioritize remediation based on their specific threat model.
The urgency for addressing this vulnerability is classified as high. Organizations must act swiftly to mitigate risks by updating the affected plugin versions or applying necessary patches to safeguard their systems.
